I haven’t seen this get a lot of attention from the folks I would have expected to hear from. This was pushed out by Microsoft just last month.
The Windows Azure Pack for Windows Server provides a solution for enterprises looking to act as service providers and service providers keen to attract enterprise workloads.
Windows Azure Pack for Windows Server is a collection of Windows Azure technologies, available to Microsoft customers at no additional cost for installation into your data center. It runs on top of Windows Server 2012 R2 and System Center 2012 R2 and, through the use of the Windows Azure technologies, enables you to offer a rich, self-service, multi-tenant cloud, consistent with the public Windows Azure experience.
A bit more context for enterprises, from a MS Whitepaper:
Enterprises are learning from the widespread, organic adoption of self-service public cloud services, choosing the agility and usage-based pricing of the public cloud over their own in-house IT operations. As a result, enterprise IT departments are looking more and more to an internal service provider model as a means of getting ‘back in the game’.
And for service providers:
For service providers, there’s a huge opportunity to host enterprise workloads now freed from the corporate datacenter. Service providers that can overcome enterprise concerns regarding their unfamiliar technology platform and workload mobility will stand a greater chance of winning enterprise business.
